powstan w drodze?????

[Gość: placek-niejacek]

how can I say:
The last thing to be dealt with in this chapter relates to the notion defined
by both [name1] and [name2].....
and here is the problem, becuase I have to paraphrase the sentence:
In cases of desynonymization one of the absolute synonyms can specialise in
its meaning.

can you tell me how can I link these two sentences,more or less:)
thanks
